Description

Technical Field

[0001] This utility model relates to the field of wood cutting technology, and in particular to an automatic tooth-clamping mechanism applied to wood cutting equipment. Background Technology

[0002] In the wood processing industry, board cutting equipment generally uses conveyor rollers to transport boards to the cutting assembly for cutting. In the early stages of board transport, this type of equipment can achieve basic positioning using the conveyor rollers and initial fixing structure. However, as the board enters the later stages of cutting, i.e., when the tail end of the board is about to leave the conveyor rollers or the initial fixing structure, the tail end of the board loses effective support and fixation. At this point, the board is susceptible to the impact and friction forces of the cutting assembly, resulting in lateral displacement or vertical swaying. This directly causes the cutting trajectory to deviate from the preset path, leading to quality problems such as uneven cut edges and dimensional deviations, making it difficult to meet the requirements of high-precision processing. The aforementioned defects in fixing during the later stages of cutting not only require substandard boards to undergo secondary processing or be scrapped directly, resulting in high board loss rates and low raw material utilization, significantly increasing production costs for enterprises; at the same time, although some equipment has attempted to add simple clamping structures such as side baffles, these structures can only limit the sides of the board and cannot provide stable longitudinal fixing for the tail end of the board, resulting in limited fixing effect. They still cannot solve the problem of cutting deviation caused by insufficient fixing in the later stages of board cutting. The industry urgently needs a stable fixing solution that can cover the entire board cutting process. Therefore, this utility model proposes an automatic tooth-clamping mechanism for wood cutting equipment to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an automatic tooth-holding mechanism for wood cutting equipment. This automatic tooth-holding mechanism fundamentally avoids board displacement and wobbling, ensures that the cutting trajectory conforms to the preset path, significantly improves the flatness and dimensional accuracy of the cut edge, and completely solves the problem of insufficient board fixation in the later stages of cutting with traditional equipment.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an automatic tooth-holding mechanism applied to wood cutting equipment, including a frame and a cutting blade sliding frame, the cutting blade sliding frame is installed at one end of the top of the frame, and both sides of one end of the cutting blade sliding frame are slidably provided with slider mounting plates, the slider mounting plates move in linkage with the cutting blade assembly, and a tooth-holding plate is provided below the slider mounting plate, and the tooth-holding plate is provided with teeth; Both sides of the top end of the frame are elastically rotatably equipped with auxiliary clamping tooth mounting plates, and one end of the auxiliary clamping tooth mounting plate is equipped with auxiliary clamping teeth.

[0005] A further improvement is that: both the upper and lower sides of one end of the cutter sliding frame are provided with opening and closing linear guide rails, and the slider mounting plate is slidably mounted on the opening and closing linear guide rails via a slider.

[0006] A further improvement is that the cutter assembly is movably mounted inside the cutter sliding frame, and cam bearings are provided on both sides of one end of the cutter assembly.

[0007] A further improvement is that both sets of slider mounting plates are provided with cam groove plates, and the inner end of the cam groove plate is provided with an inclined groove, which is adapted to the cam bearing.

[0008] A further improvement is that a protective cover is provided at one end of the cutter sliding frame, and the protective cover covers the components at one end of the cutter sliding frame.

[0009] A further improvement is that: side frames are provided on both sides of one end of the cutter sliding frame, and springs connect the two sets of side frames and the two sets of auxiliary tooth mounting plates.

[0010] The beneficial effects of this utility model are as follows: 1. This utility model forms a double fixing structure through the clamping teeth and auxiliary clamping teeth. The clamping teeth are set on the clamping tooth plate, which is connected to the slider mounting plate. The auxiliary clamping teeth are set on the auxiliary clamping tooth mounting plate, and the auxiliary clamping tooth mounting plate is elastically connected to the side frame through springs. It can flexibly adapt to the size differences of different types of boards such as solid wood boards and artificial boards. During cutting, the clamping teeth can contact the board before the cutting blade and accurately clamp the tail end of the board. The auxiliary clamping teeth provide elastic support, fundamentally avoiding board displacement and shaking, ensuring that the cutting trajectory conforms to the preset path, and greatly improving the flatness and dimensional accuracy of the cut edge. It completely solves the problem of insufficient board fixation in the later stage of cutting of traditional equipment.

[0011] 2. In this utility model, the tooth-clamping mechanism and the cutter assembly are linked. The cam bearings on both sides of the cutter assembly are adapted to the inclined grooves of the cam groove plate on the slider mounting plate. When the cutter assembly moves along the cutter sliding frame, the cam bearings slide in the inclined grooves, driving the slider mounting plate to slide smoothly along the opening and closing linear guide rail, realizing the synchronous clamping or loosening of the tooth. This linkage design does not require reducing the operating speed of the equipment to avoid vibration affecting positioning. The cutter can achieve high-frequency and fast cutting, significantly improving cutting efficiency. At the same time, the tooth can effectively fix the residual material at the tail end of the plate, completely solving the problem of the last plate being too thick or S-shaped in traditional equipment, and greatly reducing the scrap rate of unqualified plates.

[0012] 3. This utility model improves the stability of the board by using clamping teeth and auxiliary clamping teeth, reducing the secondary processing steps and scrap volume of substandard boards, directly reducing the enterprise's raw material procurement costs and waste disposal costs. At the same time, it improves cutting efficiency and shortens the production cycle, creating considerable economic benefits for the enterprise. Increased raw material utilization reduces wood waste and minimizes the indirect environmental impact of waste board disposal, aligning with the concept of green production. Furthermore, the entire clamping tooth mechanism is integrated into the frame and the cutting blade sliding frame, resulting in a compact structure that is compatible with various automated cutting production lines, making it highly practical.

[0015] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model. Example 1

[0016] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an automatic tooth-holding mechanism for wood cutting equipment, including a frame 1 and a cutting blade sliding frame 2. The cutting blade sliding frame 2 is located at one end of the top of the frame 1, and both sides of one end of the cutting blade sliding frame 2 are slidably provided with slider mounting plates 3. The slider mounting plates 3 move in conjunction with the cutting blade assembly 9. A tooth-holding plate 4 is provided below the slider mounting plate 3, and tooth-holding plates 4 are provided with tooth-holding 5. The top of the frame 1 has two elastically rotatable auxiliary tooth mounting plates 6 on both sides, and one end of the auxiliary tooth mounting plate 6 is equipped with an auxiliary tooth 7. The frame 1 provides fixed support for the entire mechanism, and the cutter sliding frame 2 serves as the mounting reference for the cutter assembly 9 and the slider mounting plate 3. For cutting solid wood or artificial boards with a thickness of 1-50mm and a width of 50-400mm, the tooth 5 moves synchronously with the slider mounting plate 3 through the tooth plate 4. After the servo conveying system completes the precise positioning of the board, the cutter assembly 9 drives the slider mounting plate 3 to slide towards each other, so that the tooth 5 contacts the board before the cutter and clamps the area to be cut. For example, when the cutting board thickness is set to 4.9mm, the tooth can firmly clamp the 9.6mm of excess material at the tail end. At the same time, the auxiliary tooth mounting plate 6, through its elastic rotation characteristics, drives the auxiliary tooth 7 to adaptively fit the side of the board, forming a double fixation with the tooth 5, avoiding lateral displacement or up-and-down shaking of the board due to impact force during cutting, laying the foundation for subsequent precise cutting.

[0017] The cutter sliding frame 2 is equipped with opening and closing linear guide rails 8 at both the top and bottom of one end. The slider mounting plate 3 is slidably mounted on the opening and closing linear guide rails 8 via a slider. The opening and closing linear guide rails 8 provide precise sliding guidance for the slider mounting plate 3. When the cutter assembly 9 drives the slider mounting plate 3 to move, the slider slides smoothly along the opening and closing linear guide rails 8, avoiding any deviation or jamming of the slider mounting plate 3. This guiding function ensures that the two clamping teeth 5 move towards or away from the board at the same time, ensuring that the clamping force of the clamping teeth 5 on the board is evenly distributed. Especially when cutting wood with a thickness of 4.7mm and a width of 200mm, it can effectively prevent uneven cutting edges caused by clamping deviation, providing a guarantee for the stability of continuously cutting 1000 boards.

[0018] The cutter assembly 9 is movably mounted inside the cutter sliding frame 2, and cam bearings 10 are provided on both sides of one end of the cutter assembly 9. The cutter sliding frame 2 provides a motion track for the cutter assembly 9, allowing the cutter assembly 9 to perform up and down cutting motion along the track; the cam bearings 10 serve as the power transmission medium between the cutter assembly 9 and the slider mounting plate 3. During equipment operation, the cutter assembly 9 and the servo conveying system form an angle match—when the cutter is at the open angle, the cam bearings 10 are at a high position with the cutter assembly 9 and do not drive the slider mounting plate 3. At this time, the servo system completes the precise conveying of the plate to a fixed length; when the cutter enters the cutting angle, the cam bearings 10 move downward with the cutter assembly 9, providing power for the subsequent drive of the clamping teeth 5 to clamp the plate, realizing the coordinated action of "conveyance-clamping-cutting".

[0019] Both sets of slider mounting plates 3 are provided with cam groove plates 15, and the inner end of the cam groove plate 15 is provided with an inclined groove 11, which is adapted to the cam bearing 10. The adaptation structure between the inclined groove 11 and the cam bearing 10 is the core drive mechanism for the opening and closing of the clamping teeth 5. When the cutter assembly 9 cuts downward, the cam bearing 10 slides along the inclined trajectory of the inclined groove 11, and pushes the cam groove plate 15 through the inclined surface force to drive the slider mounting plate 3 to move towards each other along the opening and closing linear guide rail 8, so that the clamping teeth 5 on both sides clamp the board at the same time. When the cutter assembly 9 completes the cutting and enters the return angle, the cam bearing 10 slides in the opposite direction along the inclined groove 11, driving the slider mounting plate 3 to separate in the opposite direction, and the clamping teeth 5 release the board, so that the servo system can transport the next piece of wood to be cut. This linkage structure does not require an additional power source and has a precise action response, which is one of the key technologies to increase the board yield from 88% to 95%.

[0020] Both sides of one end of the cutter sliding frame 2 are provided with side frames 13, and springs 14 are connected between the two sets of side frames 13 and the two sets of auxiliary tooth mounting plates 6. The side frames 13 provide fixed support for the springs 14, and the springs 14 maintain the auxiliary tooth mounting plates 6 with a preset contact pressure through elastic tension. When the board is conveyed to the cutting area, the auxiliary teeth 7 first contact the side of the board. The springs 14 can adaptively stretch or compress according to the actual width of the board, such as 200mm, to adjust the clamping force of the auxiliary teeth 7 and avoid fixing failure due to deviation in the width of the board. Especially when cutting the tail end of the board, the elasticity of the springs 14 can keep the auxiliary teeth 7 in contact with the board, and together with the teeth 5, prevent the board from tilting upwards, completely solving the problem of the last piece of board being too thick or S-shaped in traditional equipment, and ensuring that the cutting size error is controlled within the allowable range. Example 2

[0021] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes an automatic tooth-holding mechanism for wood cutting equipment, including a frame 1 and a cutting blade sliding frame 2. The cutting blade sliding frame 2 is located at one end of the top of the frame 1, and both sides of one end of the cutting blade sliding frame 2 are slidably provided with slider mounting plates 3. The slider mounting plates 3 move in conjunction with the cutting blade assembly 9. A tooth-holding plate 4 is provided below the slider mounting plate 3, and tooth-holding plates 4 are provided with tooth-holding 5. The top of the frame 1 has two elastically rotatable auxiliary tooth mounting plates 6 on both sides, and one end of the auxiliary tooth mounting plate 6 is equipped with an auxiliary tooth 7. The frame 1 provides fixed support for the entire mechanism, and the cutter sliding frame 2 serves as the mounting reference for the cutter assembly 9 and the slider mounting plate 3. For cutting solid wood or artificial boards with a thickness of 1-50mm and a width of 50-400mm, the tooth 5 moves synchronously with the slider mounting plate 3 through the tooth plate 4. After the servo conveying system completes the precise positioning of the board, the cutter assembly 9 drives the slider mounting plate 3 to slide towards each other, so that the tooth 5 contacts the board before the cutter and clamps the area to be cut. For example, when the cutting board thickness is set to 4.9mm, the tooth can firmly clamp the 9.6mm of excess material at the tail end. At the same time, the auxiliary tooth mounting plate 6, through its elastic rotation characteristics, drives the auxiliary tooth 7 to adaptively fit the side of the board, forming a double fixation with the tooth 5, avoiding lateral displacement or up-and-down shaking of the board due to impact force during cutting, laying the foundation for subsequent precise cutting.

[0022] One end of the cutter slide frame 2 is equipped with a protective cover 12, which covers the components at one end of the cutter slide frame 2. The protective cover 12 covers the core moving components such as the gripping teeth 5, auxiliary gripping teeth 7, and cam bearing 10 at the end of the cutter slide frame 2. During the high-frequency cutting process of the equipment, on the one hand, it can prevent wood chips from flying and causing wear on the moving components, and prevent the oblique groove 11 and cam bearing 10 from being stuck due to impurities, thus affecting the accuracy of the operation; on the other hand, it can prevent the operator from accidentally contacting the moving components, while reducing noise diffusion, providing environmental protection for the continuous and stable operation of the equipment, such as continuously cutting 1000 boards, and extending the service life of the components.

[0023] The automatic tooth-clamping mechanism applied to wood cutting equipment forms a double-fixing structure through the clamping tooth 5 and the auxiliary clamping tooth 7. The clamping tooth 5 is set on the clamping tooth plate 4, which is connected to the slider mounting plate 3. The auxiliary clamping tooth 7 is set on the auxiliary clamping tooth mounting plate 6, which is elastically connected to the side frame 13 through the spring 14. It can flexibly adapt to the size differences of different types of boards such as solid wood boards and artificial boards. During cutting, the clamping tooth 5 can contact the board before the cutting blade and accurately clamp the tail end of the board. The auxiliary clamping tooth 7 provides elastic support, which fundamentally avoids board displacement and shaking, ensures that the cutting trajectory conforms to the preset path, and greatly improves the flatness and dimensional accuracy of the cut edge, completely solving the problem of insufficient board fixation in the later stage of traditional equipment cutting. Furthermore, the tooth-clamping mechanism and the cutter assembly 9 in this product are linked. The cam bearings 10 on both sides of the cutter assembly 9 are adapted to the inclined grooves 11 of the cam groove plate 15 on the slider mounting plate 3. When the cutter assembly 9 moves along the cutter sliding frame 2, the cam bearings 10 slide in the inclined grooves 11, driving the slider mounting plate 3 to slide smoothly along the opening and closing linear guide rail 8, realizing the synchronous clamping or loosening of the tooth 5. This linkage design does not require reducing the operating speed of the equipment to avoid vibration affecting positioning. The cutter can achieve high-frequency and fast cutting, significantly improving cutting efficiency. At the same time, the tooth 5 can effectively fix the residual material at the tail end of the plate, completely solving the problem of the last plate being too thick or S-shaped in traditional equipment, and greatly reducing the scrap rate of unqualified plates. Meanwhile, this product enhances the stability of the board by using the clamping teeth 5 and auxiliary clamping teeth 7, reducing secondary processing steps and scrap volume of substandard boards, directly lowering the company's raw material procurement costs and waste disposal costs. It also improves cutting efficiency and shortens the production cycle, creating considerable economic benefits for enterprises. Increased raw material utilization reduces wood waste and minimizes the indirect environmental impact of waste board disposal, aligning with green production principles. Furthermore, the entire clamping tooth mechanism is integrated into the frame 1 and the cutting blade sliding frame 2, resulting in a compact structure that is compatible with various automated cutting production lines, making it highly practical.
